This paper presents a technique for further applications of deductive databases in the eld of natural language processing. Although there were enormous research eeorts on analyzing the semantics of natural languages (NL), especially using Montague grammars (PTQ) for Prolog, corresponding programs for deductive databases are still missing, since range restriction is required in nearly all deduct...
We describe the theory and implementation of a general theorem-proving technique for checking integrity of deductive databases recently proposed by Sadri and Kowalski. The method uses an extension of the SLDNF proof procedure and achieves the effect of the simplification algorithms of Nicolas, Lloyd, Topor et al, and Decker by reasoning forwards from the update and thus focusing on the relevant...
The ROCK & ROLL database system cleanly integrates deductive and object-oriented capabilities by deening an imperative programming language , ROCK, and a declarative, deductive language, ROLL, over a common object-oriented (OO) data model. Existing techniques for evaluation and optimization of deductive languages fail to address key requirements imposed by ROLL such as: strict typing; placement...
Finitely algebraizable deductive systems were introduced by Blok and Pigozzi to capture the essential properties of those deductive systems that are very tightly connected to quasivarieties of universal algebras. They include the equivalential logics of Czelakowski. Based on Blok and Pigozzi’s work, Herrmann defined algebraizable deductive systems. These are the equivalential deductive systems ...
Object-oriented database system supports the powerful concepts of data abstraction and complex data modeling while deductive database system has inferential and declarative query capabilities. Previous research has demonstrated the advantages and feasibilities of the confluence of the declarative logic-based paradigm and the object-oriented paradigm in the dual-paradigm system of deductive obje...
